. FREDERICK KAMPFE AND OTTO KAMPFE, OF NEW YORK, N. Y.

To (ti-l who/)1, it nut nozmern:

Be it known'that we, FREDERICK KAMPFE and OTTO KAMPF both citizens of the United States, residing in the borough of Brooklyn, in the county of Kings, city and State of New York, have invented an Improvement in Hair-Trimmers, of which the following is a specification.

Our invention relates to a device for trimming hair, althopgh-the same partakes of the character of a safety-razor.

The object of our invention is the production of a hair-cutting'implement by means of which adults may readily trim or shorten their own hair and parents the hair of their children, performing the function of a selfconstituted barber.

In carrying out our invention and in combination with a handle to be grasped by the hand and a body-frame supporting a removable razor-blade and its catchwe employ guard-combs at either side of the cutting edge of the blade. Both guard-combs are pivoted and adapted to swing over from and toward said blade, and one or-both ofthese guard-combs may be adjustable, so as to bring the free ends of the comb-teeth into the desired proximity to the cutting edge of the razor-blade. The teeth of the respective combs are advantageously in alinement. Consequently the alined intervening spaces act as ways or channels to receive and confine the hair being trimmed and revent it sliding off or getting away from t 1e cutting edge [of the razor-blade.

The body-frame at its place of support of the razor-blade is advantageously constructed with side bracket-arms for lightness and.

rigidity and to provide ample room for the hair removed in trimming and at the same time ample strength and )earing-surface for the razor-blade.

In the drawing, Figure 1 is a front eleva tion representing the device of our invention. Fig. 2 is a sideelevation of the parts shown in Fig. 1, and which figure in dotted lines the said guard-combs are shown in their overturned ositions. Fig. 3 is an elevation of the bod -frame and the parts connected therewitfi plan in smaller size ofthis body-frame, so as to show plainly the side bracket-arms there- Specification of Letters Patent.

Application filed October 2,1906. Serial No. 337,143.

for the support of with one of the guard-combs thrown up and the teeth broken oil"; and Fig. 4 is a HAIR TRIMMERQ Patented March 19, 1907. 1

of. Fig. 5 is a partial sectional plan at the dotted line at of Fig. 2. Fig. 6 is a side eleva-. tion representing a modification of ourinvention and providing means for adjusting one I of the guard-combs, and Fig. 7'is a section on the dotted line y y of Fig. 6.

' The handle a is to be grasped by the hand. It is to be made of any suitable material and is terminated with a tubular support memher a. The drawing shows the handle broken off near the tubular support member a, and it-indicates that the said handle is circular; It is therefore obvious and fully within the scope of our invention to make. this handle of any suitable material and'of any shape lengthwise or in cross-section.

The body-fran1e b is of bent configuration, as shown in Fig. 2, and is secured tothe tubular support member a by a nut 2. Figs. 3 and 4 show the broadened-out shape of the body member and the overturned portion extending at the sides to form thebracketarms I) 11 this part at the center being formed as a central curved brace b the ex treme ends of the bracket-arms being up% turned as end supports orstops I).

From theview Fig; 4, which isof'smaller size than the other parts, it-will be apparent that there is a space between the bracket-f L arms 6 b2, and this space is available in the use of the implement for. receiving the'hair removed from the head by the razor-blade e, which rests u on and is supported by the bracket-arms b is nothing below the blade to interfere. with 6 it being a fact that therethe collection of the hair as it is cut, as would bethecase if the body-frame extended across between the sides of the frame, and it is also apparent from this construction that the body-frame, with thebracket-arn'is, b I) and the centra'l brace 6 isexceedingly strongly made and provided against strain in use and at the same time is made of ample strength the razor-blade and for holding the same securely thereto.

We provide frames cd of the bent'fornf I I .100

shown especially in Figs. 2 and 3, the same being pivotally connected by the screws 3 4 near the free ends of the said bracket-arms b b and upon their outer'fares. these frames 0 d include a portion lying outside of and parallel with the outer edges of the said bracket-arms, with apart at right Eache-qef angles thereto and overturned against the upper surface of the razor-blade and with a free end comes up' against the under surface of the'bracket-arm, so as'to impart to said frames a spring fuliction to hold the razorblade in position when the said blade is passed down over the surface of the bracketarms and beneath the upper parts of said frames 'to a position in which the ends of the blade come against the supports or stops b of a said bracket-arms, and we employ a catchplate f, pivotally connected at f to the said body-frame and having a crooked portion eX-.

tending up back of the razor-blade,'s'0 as to hold the same in position and prevent accidental displacement.

Along the back of the body-frame we secure a blade-spring g by the screws 5, the same outside of said screws forming arms to bear upon the edge shoulders of the guardcomb h, which comb is secured by the pivotscrews 6 to the back of the bracket arms of the body-frame. From Fig. 2 it will be apparent that the ends of the said guardcomb h adjacent to the pivot are provided with squared edges or shoulders at right angles to one another and against which edges the said blade-spring g bears with suliicient force to hold the guard-comb h either in the full-line position or the dotted-line position, Fig. 2, and in which full-line position the free ends of the'edge' teeth of the comb rest upon the supports or stops 1) of the bodyframe, while the intermediate teeth h are positioned higher above the razor-blade and are shorter. We provide a second guard-comb i, placed in a reverse position to the guard-comb h,

and the teeth 'i of. this guard-comb and the teeth h of the guard-combh are preferably alined with oneanother, so that the alined spaces between the teeth form channels adapted to receive the hair to be cut and to be brtilght in contact with the cutting edge of the razor-blade as the instrument is drawn by hand over the hair.

The ends of the guard-comb i are formed ashprcngs or edge teeth, and they may rest agaihst the surface of the stops 1), w ile the freeends of the parallel teeth i are pre erably bent inward, so as to come below the edge of the razor-blade. This guard-comb '11 is provided with a shank i pivotally connected to a sleeve 7r by a clamp-screw 7c. This sleeve is is provided with a projection 8 and the tubular support member a of-the handle with a groove 7, receiving said projection, and the sleeve h is movable along the said tubular support member a between thei shoulders 9 10, said groove. 7 also extending between said shoulders, the groove 7 and projection 8 preventing the sleeve is turning on the member a. for a bearing relation of the teeth of the guard-comb t and the cutting edge of the razor-blade according tothe amount or depth of the instrument, and in connection with this adjustment we also provide a screw 1, l which passes transversely through the tubular support a and is at its free end adapted to bear against the inner surface of the guardcomb i, and while thesleeve k and the parts 7 and 8 provide for an adjustment of the guard-comb t in one direction the screw 1 -provides for its adjustment in the opposite direction on the screw 7:, It is to be understood that the nearer the free ends of the teeth of the guard-combs h and i come to the cutting edge of the razor-blade the more said blade is protected from direct c ontact with the hair to be cut, and consequently less hair this relation, and that the further tll'ese teeth are moved away from the cutting edge of the razor and the more said edge is exposed the more hair will be cut. I

We have shownin the modified form of our invention, Figs. 6 and 7, an adjusting-screw m, passing through a lug m, formed upon the side of the frame 0 and extending out at right angles thereto, together with a projection b from the guard-comb h to bear upon the pointed end of the said adjusting-screw, and by this means said guard-comb can he raised away from the position shown in Fig. 2 to the position shown in Figs. 6 and 7, in which the free ends of the teeth are more distant from the cutting edge of the razor, thus prol viding an adjustment for the guard-comb 7L and a corresponding function "to that of the guard-comb t. i
